Fix @typescript-eslint/no-unnecessary-type-assertion instances

[hectorgomezv]

Summary

In the process of updating to ESLint 9, some rules were temporarily ignored due to changes in their recommendations. One of these rules was the @typescript-eslint/no-unnecessary-type-assertion rule.

This PR re-enables the @typescript-eslint/no-unnecessary-type-assertion rule and addresses instances where redundant type constituents were used.

Changes

• Enable @typescript-eslint/no-unnecessary-type-assertion ESLint rule in eslint.config.mjs
